Hi, can someone help me out with this, how do I solve this matrix question:

Let A = [a,b,c; d,e,f; g,h,i] Given that detA= alpha and alpha is not equal to zero, express each of the following terms of alpha:

a) det(2A)

b) det(A^-1)

c) det [2a,2b,2c; d,e,f; g,h,i]

d) det [a,b,c; d,e,f; g,h,i]

e) det [a,b,c; d-3a, e-3b, f-3c; g,h,i]

Thank you
